Examples of java.awt.RenderingHints$Key

java.awt.RenderingHints
Defines the base type of all keys used along with the {@link RenderingHints} class to control variousalgorithm choices in the rendering and imaging pipelines. Instances of this class are immutable and unique which means that tests for matches can be made using the {@code ==} operator instead of the more expensive{@code equals()} method.

      // If the user specified a value for this hint, we don't
      // want to change that
